CORK-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 325,856, dated September 8, 1885.

Application tiled June 11, 1885. (No model.)

The object of my invention is to provide a new and improved machine for cutting cylindrical and tapering corks out of a 'piece of cork-wood, which machine is constructed to automatically feed the cork, hold the same during the operation of cutting, and eject it after it has been cut.

The invention consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter.l

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate t corresponding parts in all the figures.

Figure l is a side view of my improved corkcutting machine. Fig. 2 is aplan view of the same. Fig. 3 is an end view of the same. Fig. 4 is a cross-sectional elevation of the same. Fig. 5 shows detail sectional views of the cutters. l

The machine is provided with two end standards, A, united by atop plate, A', having end lugs held by screws (shown in dotted lines in Fig. l) on the tops of the standards, thus permitting of adjusting the top plate, A', higher or lower on the end standards.

On the top plate, A', two standards, B, are secured, vand in the same a tubular shaft, C, is mounted to slide and revolve on its longitudinal axis, on which tubular shaft is mounted a belt-pulley, C', for revolving said shaft.

On the shaft C a sleeve, D, is heldby a setscrew, D', and the said sleeve is provided with an exterior collar, E, which is surrounded by two clamping devices, F, having pivots F', which are in the forked upper end, G', of alever, G, having its lower end connected with a spring, H, which presses the said lever against a cam, I, on a shaft, J, journaled in the frame of the machine, and provided at one end with a bevel cogwheel, J', engaging with a bevel cog-wheel, K', on4 one end of a shaft, K. On Ithe shaft J the fixed and loose belt-pulleys 1 and l2 are mounted.

A rod or holder, L, is passed longitudinally through the tubular shaft C, and has one end held adjustably in the upper end of a lever, N, pivoted on one of the endvuprghts A, and having its lower end connected with a spring, N', which presses the lower end ofsaid lever N against a cam, N2, also on the shaft J.

A rod, P, held to slide in suitable guides, P', on the top frame, has one end bent rectangularly and connected with the upper end of the lever N.-

On that end of the shaft K opposite the one 0n which the bevel cog-wheel K' is mounted an arm, M, is secured transversely, and is provided with a longitudinal slot, in which a pivot, M', is held adjustably, which pivot is connected by a rod, O, with a rocking lever, Q, mounted on the end of a shaft, Q', carrying the lower feed-roller, R'. On the same shaft is mounted a ratchet wheel, S, with whicha pawl, T, pivoted to the upper end of the rod O can engage. The upper feed-roller, R, resting directly above the lower roller, is journaled in blocks U, mounted to slide vertically tin guides U', and pressed down by springs. The piece of cork m, from which the corks are to be cut, slides along the partition V, provided at the end of the rod P with an aperture, W. e

Opposite the 'end of the tubular shaft G a plate, Y, is held by screws on the said partition V. The shaft Gis provided on its end with a head, G2, or socket for receiving the cutter-head, which is made of steel and is hol- 10W.

For cylindrical corks the cutter consists of an ordinary tube, a. For tapered corks it consists of the tube b, having a shoulder, c, from which a flaring part, d, projects, the said flaring part being provided in its end with notches and in its sides with slots, which form cutting-edges.

The operation is as follows: The shaft J is revolved by means of a belt on the fixed pulley on said shaft, and by means of the bevelgear revolves the shaft K. The cutter-shaft is revolved by means of a separate belt on the pulley C'. As the cam I acts on the lever G,

lthe cutter a on the end of the tubular shaft C is forced into the piece of cork 'm until the end of the cutter abuts against the plate Y.

Then the cutter is withdrawn as the cam I slides off the lever G, and the spring H can act on the lower end of the lever G in such amanner as to Vwithdraw the cutter. Before the cutter begins to cut through the cork, the rod L has been acted upon by the lever N in such a manner that the end of said rod lis pressed against the piece of cork and holds that part which is being cut out by the cutter. The rod L'is then withdrawn, and by this time the shaft K is revolved to such an extent that the rod O has swung downward and the lower feed-roller is revolved and the cork is fed forward. During the time that the cutting takes place the rod O swings upward and the feed-Y rollers are not revolved. The rod l?, which is the ejector, moves in the same direction as the rod L at the same time that said rod moves, and at the time that the rod L is being moved forward for the purpose of following the cork to be cut the rod I? forces the cut cork out of thepiece of wood in which ithas been carried forward and through the aperture W. The machine thus feeds the cork automatically, cuts it, holds it during the time it is being cut, andejects the completed cork.

Gutters of any desired taper, shape, or size can be used, and the machine can be adjusted to feed the block of cork forward a greater or less distance, as circumstances may require, by adjusting the pivot M in the cross-bar M a greater or less distance from the shaft K.

Having thus fully described my invention, I cla-i 1n as new and desire to secure by Letters Patent-n 1. In a corkcutting machine, the combination, with asliding and revolving tubular shaft, of a rod passed loosely through the same, a pivoted lever connected with the rod passed through the tubular shaft, a cam acting on said lever, a rod for pushing out the cores of corks cut out of the piece of cork by the cutter, which pushing-rod is connected with the rod passed through the cutter, so as to move with the same, substantially as herej in shown and described.

, on said lever, substantially as herein shown and described.

3. In a cork-cutting machine, the combination, with a shaft, K, of the lever G, operated from the shaft K by means of suitable gearing and cams, a sliding revolving tubular shaft held in the upper forked end of the lever G, and the upper and lower feed rollers, It and R', of which the latter is operated from the shaft K by means of suitable devices, substantially as herein shown and described.

4. A cork-cutting machine provided with a sliding revolving tubular shaft for holding a cutter, a pivoted lever connected with said tubular shaft, and a cam actingrion said lever, substantially as herein shown and described.

5. In a cork-cutting machine, the combination, with the frame, of a sliding and revolving tubular shaft for carrying the cutter, a pivoted lever connected with the shaft, a cam acting on the lever, a rod passed through the shaft for the purpose of holding the cork in place during the time the same is being-cut, a lever connected with said rod, and a cam acting on the lever,`substantially as herein lsh own and described.

6. In a cork-cutting machine, the combination, with a sliding revolving tubular shaft, of a rod passed through the same, a lever connected with the rod, a pushing-rod connected with said lever, and feed-rollers for moving the cork past the cutter on the end of the tubular shaft, the said rods and feeding devices being operated from the same shaft, substantially as herein shown and described.

7. In a cork-cutting machine, the combination, with a shaft, K, of the pivoted lever G, operated from the'same, a sliding revolving tubular shaft held on said lever G, the feedrollers R and R, the ratchet-wheel S on the shaft of the latter, the rocking lever Q, the pawl T, and the cross-piece M on one end of the shaft K, inwhich cross-piece the lower end of the rod O is held adjustably, substantially as herein shown and described.

8. In a cork-cutting machine, the combination, with the frame having the partition V, provided with the aperture W', of a sliding revolving tubular shaft carrying the cutter, a rod passed through the shaft, and a pushingrod having one end opposite the aperture W, substantially as herein shown and described.
